BACKGROUND OF THE INVENTION
Field of the Invention
[0001] The present invention relates to a kind of furniture, and more particularly, to a
piece of height adjustable furniture.
Description of the Related Art
[0002] Common furniture includes tables and chairs. In view of the differences in habits,
locations and users, tables and chairs with a variety of heights are usually needed.
Taking a dining table and a tea table as examples, they have a great difference in
height because of various heights users may sit at, though they both belong to tables.
As another example, at a buffet or an outdoor barbecue, a table for placing foods
shall have a height suitable for users to stand and take foods easily, while a dining
table shall have a height suitable for users to sit. Similarly, different users have
different heights as well as different leg lengths, so the heights of chairs most
suitable for each person to sit on also vary. A high chair may keep the feet of a
short user suspended, greatly reducing the user experience and the degree of comfort;
a short chair cannot help a tall user effectively relax and rest when the user sits
for a long time, because the thighs cannot be effectively supported by the seat.
[0003] However, conventional tables and chairs usually have only a fixed height, so the
function is single. To meet different demands, it is common that tables and chairs
with a variety of heights are purchased and placed in homes and public places. This
occupies a very large space and increases costs, and also makes it difficult to achieve
uniformity in appearance and style. A known piece of height adjustable furniture is
disclosed in
DE 20 2016 101 290 U.

DETAILED DESCRIPTION OF THE INVENTION
[0018] The present invention provides a piece of height adjustable furniture, comprising
a bearing surface 1, a support assembly 2, a switch 3, at least one adjustment wire
4, a pneumatic damper 5, and at least one positioning assembly 6. In this embodiment,
the height adjustable furniture shown in the figure is a table. However, the invention
is not limited thereto. In other embodiments, the height adjustable furniture may
be a chair.
[0019] In this embodiment, the bearing surface 1 can be made of boards, glass or rattan.
If the bearing surface 1 is made of rattan, the bearing surface 1 will be firm, light,
tough and pliable in texture, soft to the touch, delicate in appearance and capable
of taking a variety of shapes. The use of rattan retains the original color of the
rattan, greatly reducing the environmental pollution caused by chemical fiber, plastics,
paints, coatings, adhesives and other chemicals, so that the furniture is more environmentally
friendly. However, the invention is not limited thereto. The height adjustable furniture
provided by the present invention is suitable for furniture made of any materials.
In this embodiment, the bearing surface 1 is a table top. In case the furniture of
the present invention is a chair, the bearing surface 1 is a surface of the seat.
The seat made of rattan has better permeability than that made of boards and glass,
so it makes users feel cooler in summer.
[0020] In this embodiment, the support assembly 2 is disposed at one side of the bearing
surface 1 to support the bearing surface 1. Specifically, when the height adjustable
furniture is in use, the support assembly 2 is disposed under the bearing surface
1. In actual application, the support assembly 2 can form a circle to surround the
adjustment wire 4, the pneumatic damper 5 and the positioning assembly 6, thereby
bringing a finer appearance and also protecting the internal structure by preventing
foreign objects from entering or causing accidental damage to the internal structure.
[0021] In this embodiment, the support assembly 2 includes a first support element 21 and
a second support element 22. The first support element 21 is sleeved on the second
support element 22, and the second support element 22 is fixed to the bearing surface
1. When the bearing surface 1 rises, the second support element 22 rises along with
the bearing surface 1 relative to the first support element 21. Through this arrangement,
the internal structure inside is always surrounded by the support assembly 2 regardless
of the height at which the furniture is, thereby ensuring an aesthetic appearance
and protecting the internal structure from any accidental damage caused by external
objects. However, the invention is not limited thereto. In other embodiments, the
support assembly 2 may only include a first support element 21, and when the bearing
surface 1 rises, the bearing surface 1 can separate from the first support element
21 to rise. In another embodiment, the support assembly 2 can only include a second
support element 22, and when the bearing surface 1 rises, the bearing surface 1 rises
along with the second support element 22. In this case, the support assembly 2 can
also be disposed to have a support frame so as to support the raised bearing surface
1 and the second support element 22.
[0022] In actual application, both the first support element 21 and the second support element
22 can be made of rattan, so as to provide a variety of shapes, make the support assembly
2 firm and light, and also bring a finer appearance.
[0023] In this embodiment, the support assembly 2 can further include a first fixing element
211 and a second fixing element 221. The first fixing element 211 is disposed in the
first support element 21, and the second fixing element 221 is disposed in the second
support element 22. In this embodiment, the first fixing element 211 and the second
fixing element 221 are rectangular fixing frames. However, the invention is not limited
thereto. In case the furniture provided in the present invention application is a
round table, the first fixing element 211 and the second fixing element 221 can be
round fixing frames. By the first fixing element 211 and the second fixing element
221, the relative position of the first support element 21 and the second support
element 22 can be accurately designed, regardless of the shape of the first support
element 21 and the second support element 22, which facilitates the manufacture and
maintenance. Meanwhile, in case the first support element 21 and the second support
element 22 are made of rattan, the rattan can surround the first fixing element 211
and the second fixing element 221 for fixing.
[0024] A switch 3 is disposed at the support assembly 2. In this embodiment, the first support
element 21 is made with a hole through which the switch 3 is disposed. In this embodiment,
the switch 3 is a pedal switch which is convenient for users to operate and enables
users to easily apply sufficient force to disengage a second positioning element 62
away from the engaging position with a first positioning element 61. However, the
invention is not limited thereto. In other embodiments, the switch 3 may be a hand-press
switch.
[0025] One end of the adjustment wire 4 is connected with the switch 3, and the other end
is connected with the second positioning element 62 of the positioning assembly 6.
In this embodiment, the adjustment wire 4 may be a steel wire. However, the invention
is not limited thereto, and the adjustment wire 4 can be made of any materials capable
of bearing a certain pulling force. When the switch 3 is pressed, the adjustment wire
4 will be pulled. In this embodiment, both the number of the positioning assemblies
and the number of the adjustment wires are four. By the four adjustment wires 4 and
four sets of positioning assembly 6, four corners of the furniture can be positioned,
thereby making the positioning firmer and more reliable. Correspondingly, the switch
3 may have four engaging grooves 31 for engaging the four adjustment wires 4 respectively,
so that the four adjustment wires 4 are driven as the switch 3 is pressed.
[0026] One end of the pneumatic damper 5 is fixed to the bearing surface 1. Specifically,
the pneumatic damper 5 is disposed under the bearing surface 1, and the other end
of the pneumatic damper 5 is fixed to the bottom of the furniture. When the furniture
is in the lowest position, gas inside the pneumatic damper 5 is in a compressed state,
and when the second positioning element 62 is disengaged away from the engaging position
with the first positioning element 61, the gas inside the pneumatic damper 5 pushes
a pneumatic rod to rise thus to push the bearing surface 1 to rise. By use of the
pneumatic damper, the furniture provided by the present invention can be raised and
lowered without any motors. That is, there is no need for any power supply. Being
energy-saving and environmentally-friendly, and the furniture can be used anywhere
in the outdoors.
[0027] The present invention is not intended to limit the position and number of the pneumatic
damper 5. In this embodiment, the pneumatic damper 5 is disposed at the center of
the bearing surface 1, so that the entire bearing surface 1 remains as horizontal
as possible as the bearing surface 1 rises. When the bearing surface 1 is large, a
pneumatic damper 5 can be disposed in two symmetrical positions respectively to realize
a stable rise of the bearing surface 1.
[0028] In this embodiment, the support assembly 2 can further include a third fixing element
231 fixed to the bottom of the first support element 21, and one end of the pneumatic
damper 5 is fixed under the bearing surface 1, with the other end fixed to the third
fixing element 231.
[0029] The positioning assembly 6 includes the first positioning element 61 and the second
positioning element 62 capable of engaging with each other, and the first positioning
element 61 is located at the support assembly 2. In this embodiment, the first positioning
element 61 is a positioning hole or a positioning groove, and the second positioning
element 62 is a positioning pin. When the positioning pin is inserted into the positioning
hole or embedded into the positioning groove, the first positioning element 61 and
the second positioning element 62 are fixedly engaged. However, the invention is not
limited thereto. In other embodiments, the first positioning element may be a positioning
pin, and the second positioning element may be a positioning hole or a positioning
groove. That is, the positions of the two structures can be exchanged. Furthermore,
the present invention is not intended to limit the specific structures of the first
positioning element and the second positioning element. Any two structures which can
match with each other to realize the positioning can constitute the positioning assembly
6 of the present invention.
[0030] Specifically, in this embodiment, the positioning hole may be a slotted hole, which
can appropriately reduce the accuracy requirements of the engaging positions in the
horizontal direction, thereby reducing the design and manufacturing costs and avoiding
the non-engagement between the first positioning element 61 and the second positioning
element 62 resulting from a slight relative movement of the first support element
21 and the second support element 22 in the horizontal direction. Specifically, in
case the ground is not completely flat, the slotted hole can also be vertically made,
which can also appropriately reduce the accuracy requirements of the engaging positions
in the vertical direction, thereby greatly improving the applicability of the furniture
to various occasions.
[0031] In this embodiment, the height adjustable furniture includes four positioning assemblies
6, wherein each positioning assembly 6 includes three first positioning elements 61
and one second positioning element 62, and the second positioning element 62 can respectively
engage with each of the three first positioning elements 61. In this embodiment, the
three first positioning elements 61 are distributed along the height direction of
the support assembly 2, that is, they are successively disposed from top to bottom
in the vertical direction. The three first positioning elements 61 are positioned
corresponding to three heights which the furniture can be adjusted. In other embodiments,
in case the height of the furniture needs to be adjusted obliquely, three first positioning
elements may be disposed in the vertical direction in a tilted state.
[0032] In other embodiments, the positioning assembly 6 may only include one first positioning
element and one second positioning element. In that case, the engagement between the
first positioning element and the second positioning element makes the first furniture
height, and the non-engagement between the first positioning element and the second
positioning element makes the maximum height to which the pneumatic damper 5 can raise
the furniture at the second furniture height.
[0033] In this embodiment, the three first positioning elements 61 can be located on the
first fixing element 211, and the second positioning element 62 can be fixed to the
second fixing element 221. By the first fixing element 211 and the second fixing element
221, the engaging positions of the first positioning elements 61 and the second positioning
element 62 can be accurately designed and laid out. Furthermore, in case the first
support element 21 and the second support element 22 are made of rattan, it is not
easy to open a positioning hole on the rattan. By provision of the additional fixing
elements, it is possible to simplify the mounting structure and facilitate the maintenance,
realizing the fixing function as well. However, the invention is not limited thereto.
In other embodiments, if the furniture is made of boards, holes can be directly drilled
in the boards to form the positioning holes.
[0034] In this embodiment, when the second positioning element 62 is inserted into the first
positioning element 61, the engaging structure formed by the two elements limits the
movement of the second support element 22 relative to the first support element 21
in the height direction, so that the furniture height is unchangeably fixed. When
users want to adjust the furniture height, they can pull the second positioning element
62 out of the first positioning element 61 through the adjustment wire 4, enabling
the movement of the second support element 22 relative to the first support element
21 in the height direction. At that time, the height can be adjusted under the force
of the pneumatic damper 5.
[0035] Particularly, in this embodiment, the support assembly 2 further includes a snap
joint 241 which is fixed to the second fixing element 221. The snap joint 241 movably
matches with the first fixing element 211. That is, the first fixing element 211 is
not fixed to the snap joint 241, so that the snap joint 241 can slide on the surface
of the first fixing element 211 as the second fixing element 221 rises. By the snap
joint 241, the relative movement path of the first fixing element 211 and the second
fixing element 221 can be limited, so that during the rise, the second positioning
element 62 will definitely rise along the vertical distribution path of the first
positioning elements 61 thus to realize an accurate engagement every time. Meanwhile,
the snap joint 241 also limits the relative movement of the first support element
21 and the second support element 22 in the horizontal direction.
[0036] In this embodiment, the adjustment wire 4 includes a wire sleeve 41 and the positioning
assembly 6 further includes a clamping element 63 which is disposed corresponding
to the second positioning element 62 and clamps the wire sleeve 41. Since the adjustment
wire 4 is not necessarily linearly distributed inside the furniture, the wire sleeve
41 can fix the movement path of the adjustment wire 4 so as to facilitate calculating
the movement travel of the adjustment wire 4 when the switch 3 is pressed, thereby
ensuring that the movement travel of the adjustment wire 4 is sufficient to release
the engagement between the first positioning element 61 and the second positioning
element 62. Meanwhile, the wire sleeve 41 also protects the adjustment wire 4 from
wear resulting from the friction with the external during wiring. However, the invention
is not limited thereto. In other embodiments, the adjustment wire 4 may not include
the wire sleeve 41, and a winding post can be disposed inside the furniture to realize
the arrangement of the adjustment wire 4 instead.
[0037] In this embodiment, the positioning assembly 6 further includes a conduit 64, and
the second positioning element 62 is disposed through the conduit 64. The conduit
64 can be fixed to the second fixing element 221 to limit the movement direction of
the second positioning element 62, making the second positioning element 62 move in
only two directions which are away from and toward the first positioning element 61.
[0038] The positioning assembly 6 further includes an elastic element 65 disposed at one
end of the second positioning element 62. The elastic element 65 may be a spring sleeved
on one end of the second positioning element 62. When the second positioning element
62 is pulled in the direction away from the first positioning element 61, the elastic
element 65 is compressed. When the external pulling force is removed, the elastic
element 65 pushes the second positioning element 62 to move toward the first positioning
element 61. By the elastic element 65, the first positioning element 61 and the second
positioning element 62 can be repeatedly engaged and disengaged, so as to realize
automatic locking of the furniture at multiple heights as well as automatic locking
of the furniture rising and lowering.
[0039] The positioning assembly 6 further includes a stop element 66 disposed on one side
of the elastic element 65. Specifically, the first positioning element 61 is a positioning
pin with both ends having different diameters, wherein the larger-diameter end faces
the first positioning element 61. The interior diameter of the elastic element 65
is between the diameters of the two ends of the second positioning element 62. Both
the elastic element 65 and the stop element 66 are sleeved on the smaller-diameter
end, and the elastic element 65 is located between the larger-diameter end and the
stop element 66. When the second positioning element 62 is pulled away from the first
positioning element 61 via the adjustment wire 4, the second positioning element 62,
the elastic element 65 and the stop element 66 move rightward, as shown in FIG. 5,
until the stop element 66 reaches the clamp part 63. At that time, the stop element
66 does not move, and the elastic element 65 is compressed. When the pulling force
is removed from the adjustment wire 4, the elastic element 65 pushes the second positioning
element 62 to move toward the first positioning element 61. In actual application,
one end of the second positioning element 62 may be threaded, the stop element 66
may be a nut, and the stop element 66 is connected to the threaded end of the second
positioning element 62.
[0040] The way of adjusting the height of the furniture provided in this embodiment is described
in detail hereinafter. As shown in FIG. 7A and FIG. 8A, when the furniture is in the
lowest position, the second positioning element 62 engages with the lowermost first
positioning element 61. At that time, the gas inside the pneumatic damper 5 is in
a compressed state. Then, a user presses the switch 3 with his or her foot. The switch
3 is pressed to pull the adjustment wire 4 at one end. The other end of the adjustment
wire 4 pulls the second positioning element 62 away from the engaging position with
the lowermost first positioning element 61, causing the elastic element 65 to be compressed
and store energy. Under the condition of lack of external resistance, the gas inside
the pneumatic damper 5 pushes the pneumatic rod to move upward. At that time, the
second support element 22 and the bearing surface 1 rise, and the second positioning
element 62 located on the second support element 22 rises as well. When the user moves
his or her foot away from the switch 3, the elastic element 65 pushes the second positioning
element 62 to move toward the first positioning element 61, until the second positioning
element 62 rises to touch the first poisoning part 61 and the first positioning element
61 located in the middle in the vertical direction re-engages with the second positioning
element 62. At that time, the furniture is at the second height, as shown in FIG.
7B and FIG. 8B.
[0041] If the user wants to further increase the furniture height, he or she can continue
to press the switch 3 with his or her foot, so that the switch 3 is pressed to pull
the adjustment wire 4 at one end. The other end of the adjustment wire 4 pulls the
second positioning element 62 away from the engaging position with the middle first
positioning element 61, causing the elastic element 65 to be compressed and store
energy. Under the condition of lack of external resistance, the gas inside the pneumatic
damper 5 pushes the pneumatic rod to move upward. At that time, the second support
element 22 and the bearing surface 1 rise, and the second positioning element 62 located
on the second support element 22 rises as well. When the user moves his or her foot
away from the switch 3, the elastic element 65 pushes the second positioning element
62 to move toward the first positioning element 61, until the second positioning element
62 rises to touch the first poisoning part 61 and the first positioning element 61
located uppermost in the vertical direction re-engages with the second positioning
element 62. At that time, the furniture is at the third height, as shown in FIG. 7C
and FIG. 8C.
[0042] If the user wants to reduce the furniture height, he or she can keep stepping on
the switch 3 and press the bearing surface 1 with hands against the pressure of the
pneumatic damper 5, until the second positioning element 62 engages with the first
positioning element 61. In other embodiments, the three first positioning elements
61 can be located on the second support element 22, and the second positioning element
62 can be fixed to the first support element 21, so as to realize the engagement of
the two elements and the height adjustment of the furniture. To sum up, the furniture
of the present invention provided with the positioning assembly can be designed to
have different adjustable heights according to actual demands. By the pneumatic damper,
the furniture height can be increased or reduced without a power supply. Being simple,
easy to assemble and not restricted by sites, the furniture enjoys a wide application.
The furniture with a variety of adjustable heights in the invention can be used for
different users and occasions to realize multi-function of products and can reduce
costs and space as it can be used as a dining table and as a tea table.
